The following fields had no data for any of the selected robots: Running Capable, Payload (Peak), Grip Strength, Manipulation Repeatability, Tool Use, Teleoperation, Battery Capacity, Charging Time, Charging Method, Avg Power Consumption, Force-Limited Arms, Fall Recovery, Fall Detection Response, Emergency Stops, Safe Speed Near Humans, Simulation Platforms, MTBF, Task Success Rate, Noise Level, RaaS / Month, Developer Unit Price, Delivery Lead Time, Production Pilots
ROI Comparison
Same operating assumptions across every robot — the only difference is price. Set your numbers once to see which pays back fastest.
Annual labor displaced (per robot): $50,000
| Metric | Darwin-OP | Eva |
|---|---|---|
| Investment | $12,000 | $23,000 |
| Payback period | 2.9 mo | 5.5 mo |
| Net savings (5 yr) | $238,000 | $227,000 |
| ROI (5 yr) | +1983% | +987% |
Estimates labor-cost displacement only — not a full total cost of ownership. Actual ROI depends on integration, maintenance, training, downtime, and task fit. Converted currencies are indicative; USD is the price of record.
